Description
Immobiliser antenna for Citroën and Peugeot vehicles with multiplex network. Attention – compatibility with your vehicle should be checked.
Product Overview
This transponder/immobiliser antenna (immobilizer antenna) is designed for Citroën and Peugeot vehicles. It reads the key transponder signal at the ignition area and communicates with the vehicle’s immobiliser system to allow engine start. Commonly referenced by OE numbers 9663123280 and 6160C0, this antenna is a direct-fit electrical component used in multiplexed vehicle networks on a range of Stellantis models.
Why Professionals Choose This Part
For technicians and DIY enthusiasts, this antenna offers a straightforward replacement solution when the vehicle reports immobiliser faults or fails to recognise the key. Installing the correct antenna restores reliable transponder reading and reduces no-start issues caused by poor signal reception, corrosion or wiring damage around the steering column.
Common Symptoms And Failure Modes
- Vehicle Won’t Start Or Intermittent Cranking — The immobiliser cannot read the transponder key.
- Immobiliser Warning Lights Or Messages — Fault codes related to the immobiliser/antenna loop.
- Poor Key Recognition Or Intermittent Lockout — Often caused by damaged coil, connector issues or wiring faults.
- Failure Caused By Mechanical Damage — Steering column disassembly, impact or foreign objects can damage the antenna ring.
- Electrical Degradation — Corrosion, moisture ingress or broken solder joints reduce signal strength.
Installation And Service Advice
Typical replacement is accessible from the steering column area. Recommended steps for a safe and effective swap:
- Disconnect the Battery Before Any Work On The Ignition Or Electronic Circuits.
- Remove Steering Column Covers To Expose The Ignition Barrel And Antenna Assembly.
- Unplug The Antenna Connector Carefully And Note Connector Orientation For Reassembly.
- Remove The Old Antenna Coil From Around The Ignition Barrel And Fit The New Unit In The Same Position.
- Reassemble Column Covers And Reconnect The Battery. Perform A Functional Check With Original Keys.
In most cases the antenna itself is a plug-and-play component and does not require coding. If problems persist after replacement, verify the immobiliser control unit, key transponder health and wiring continuity.

Why This Part Fails Most Often
Failures are typically caused by physical damage during steering column service, connector corrosion, moisture ingress, or intermittent wiring faults. The antenna coil itself rarely “wears out” electrically but can be rendered non-functional by mechanical deformation, shorted turns or broken internal connections.
Suitability And Notes For Technicians
Use the OE reference numbers 9663123280 and 6160C0 when searching or ordering to ensure correct fitment. This part is intended for vehicles equipped with a multiplex data network; confirm that the listed models match the vehicle’s equipment level and ignition configuration.
Purchase Tip
Keep the original part number to hand when replacing the immobiliser antenna. Supplying the OE codes speeds up sourcing the correct unit and avoids diagnostic time on site.
